Anestesia de um Graxaim-do-campo (Pseudalopex gymnocercus) com propofol por infusão contínua Pampas fox (Pseudalopex gymnocercus) anesthesia with propofol by continuous infusion

Pampas fox (Pseudalopex gymnocercus) is a Wild-life canid that lives in the South Region of Brazil. It is known very little about this kind of species anesthesia, but it is believed to be similar to that used in domestic dogs. The propofol , widely used in dogs, is an injectable anesthetic distinct from other anesthetic drugs, which provides rapid induction, good recovery with minimum residual effect. In this study, propofol was used by continuous infusion for bone implant removal in a 4.5kg graxaim. Before starting the general anesthesia it was used as pre-medication tiletamine-zolazepam, pethidine hydrochloride and fentanil citrate, all by intramuscular. After tranquilization and containment, there was made a pre-anestheti c evaluation of the animal. The patient was induced with a dose of 4mg/kg, IV propofol to obtain the desired anesthetic effect. Immediately after the induction, began continuous infusion of propofol at a 0.35mg/kg/h dose for maintenance. The anesthetic procedure lasted one hour and twenty minutes, with parameters, ocular reflex, heart rate, respiratory frequency, mean arterial pressure and oximetry, was evaluated every ten minutes. The objective of this report was to assess changes in cardiovascular and respiratory in the protocol used, as well as the functionality of the technique. The decrease in the mean arterial pressure and respiratory depression were striking in the procedure, but the technique shown to be viable and the doses of the drug were effective and adequate, although they require a specific structure and equipment.
